I don't miss smoking, and have been vaping for 2 years.
Then again, I am one that allows myself to smoke and do still have an occasional smoke. IOW, I do both. Around 85% vaping and 15% time smoking, on average.
When I quit cold turkey (in my 20's) for 8.5 years, I very rarely missed smoking then, while feeling very confident I wouldn't have one and while always giving myself permission to have one. Didn't need to hate on smoking to enjoy my life of non-smoking then. Why vapers feel a need to hate on smoking is bizarre to me, but I kinda sorta think I know what is going on there.
I can name 3 to 5 pros that smoking has that vaping doesn't. Some have already been brought up in this thread. Just yesterday when I had a great experience with a log, I felt that a log satisfies in a way that vaping can't. Likewise, I get to experience many times where vaping satisfies in a way that (currently) smoking can't, such as I get to vape indoors with almost no questions asked.
I really like being a light smoker. There are times when I have 2 to 3 left in a pack going into the night and I'm never frantic. Back in smoking-only days, that would've been cause for anxiety and wondering how I'll make it that night and early the next day. Not anymore. I also look forward to the occasional smoke, and after 2 years of doing both, have no inkling that I may move back to a pack a day, heavy smoking. About the most logs I've smoked in past year was half pack in one day. 2 to 3 days after that, I had zero.
Just as there are thousands of vapers who wish smokers would give up their, ahem, nasty habit and make the full switch, I'm the type of vaper that wishes most, if not all vapers, still had 1 log every day or every other day. Maybe then 'we' could stop throwing smokers under the political bus, which just so happens to make it easier for ANTZ to throw all nicotine addicts under that same bus. At least as far as current politics go.
